FIELD

Provided herein are compounds that exhibit activity as acetyl-CoA carboxylase modulators (e.g., inhibitors) and are useful, for example, in methods for the control of fungal pathogens and diseases caused by fungal pathogens in plants.

BACKGROUND

Acetyl-CoA carboxylase (“ACCase”) is an essential catalyst for the rate-limiting step of fatty acid biosynthesis in both eukaryotes and prokaryotes. Phytopathogenic fungi can infect crop plants either in the field or after harvesting, resulting in considerable economic losses to farmers and producers worldwide. In addition to the agricultural impact, when food and feed contaminated with fungi or the toxins they produce are ingested by humans or livestock, a number of debilitating diseases or death can occur. Approximately 10,000 species of fungi are known to damage crops and affect quality and yield. Crop rotation, breeding of resistantcultivars, the application of agrochemicals and combinations of these strategies is commonly employed to stem the spread of fungal pathogens and the diseases they cause. Additional chemistry and methods of using such as a modulator for ACCase or to control fungi are important for, among other things, protection in agriculture.

For example, the rapid onset of resistance to chemical fungicides has often lowered the efficacy of some chemical fungicides. This threat, as well as emergence and spread of additional fungal diseases, accentuates the need for new means of fungal control.

The seed treatment methods described herein may be used to modulate, inhibit, and/or control any of the fungal pathogens and/or plant diseases described above. In one embodiment, the method comprises treating a seed with a composition comprising a compound as described herein. As used herein, the term “seed” broadly encompasses plant propagating material such as, tubers cuttings, seedlings, seeds, and germinated or soaked seeds.

In one embodiment, the disclosure relates to a method of administering to a seed a compound (e.g., a compound of Formula I, Ia, Ib, II, IIa, IIb, IIc, IId, III, or IV) as described to control fungal pathogens in a composition as described herein, including using the compounds as described herein with the any adjuvants, excipients, or other desirable components as described herein or known in the art and formulating, mixing, or combining one or more additional active ingredients. The additional active ingredient may be, for example, an additional pesticide. The pesticide may be, for example, an insecticide, a fungicide, an herbicide, or an additional nematicide as described herein or otherwise known in the art.

For example, a compound as described herein may be applied to seeds or tubers by impregnating them with a liquid seed treatment composition comprising a compound described herein, or by coating them with a solid or liquid composition comprising a compound described herein.

Seed treatment methods described herein can be used in connection with any species of plant and/or the seeds thereof as described herein. In some embodiments, however, the methods are used in connection with seeds of plant species that are agronomically important. In particular, the seeds can be of corn, peanut, canola/rapeseed, soybean, cucurbits, crucifers, cotton, beets, rice, sorghum, sugar beet, wheat, barley, rye, sunflower, tomato, sugarcane, tobacco, oats, as well as other vegetable and leaf crops. In some embodiments, the seed is corn, soybean, or cotton seed. The seed may be a transgenic seed from which a transgenic plant can grow and incorporate a transgenic event that confers, for example, tolerance to a particular herbicide or combination of herbicides, insect resistance, increased disease resistance, enhanced tolerance to stress and/or enhanced yield. Transgenic seeds include, but are not limited to, seeds of corn, soybean and cotton.

A seed treatment method may comprise applying a composition to the seed prior to sowing the seed, so that the sowing operation is simplified. In this manner, seeds can be treated, for example, at a central location and then dispersed for planting. This permits the person who plants the seeds to avoid the complexity and effort associated with handling and applying the compositions, and to merely handle and plant the treated seeds in a manner that is conventional for regular untreated seeds.

A composition can be applied to seeds by any standard seed treatment methodology, including but not limited to mixing in a container (e.g., a bottle or bag), mechanical application, tumbling, spraying, immersion, and solid matrix priming. Seed coating methods and apparatus for their application are disclosed in, for example, U.S. Pat. Nos. 5,918,413; 5,891,246; 5,554,445; 5,389,399; 5,107,787; 5,080,925; 4,759,945 and 4,465,017, among others. Any conventional active or inert material can be used for contacting seeds with the composition, such as conventional film-coating materials including but not limited to water-based film coating materials.

For example, in one embodiment, a composition can be introduced onto or into a seed by use of solid matrix priming. For example, a quantity of the composition can be mixed with a solid matrix material and then the seed can be placed into contact with the solid matrix material for a period to allow the composition to be introduced to the seed. The seed can then optionally be separated from the solid matrix material and stored or used, or the mixture of solid matrix material plus seed can be stored or planted directly. Non-limiting examples of solid matrix materials which are useful include polyacrylamide, starch, clay, silica, alumina, soil, sand, polyurea, polyacrylate, or any other material capable of absorbing or adsorbing the composition for a time and releasing the active compound of the composition into or onto the seed. It is useful to make sure that the active compound and the solid matrix material are compatible with each other. For example, the solid matrix material should be chosen so that it can release the active compound at a reasonable rate, for example over a period of minutes, hours, days, or weeks.

Imbibition is another method of treating seed with the composition. For example, a plant seed can be directly immersed for a period of time in the composition. During the period that the seed is immersed, the seed takes up, or imbibes, a portion of the composition. Optionally, the mixture of plant seed and the composition can be agitated, for example by shaking, rolling, tumbling, or other means. After imbibition, the seed can be separated from the composition and optionally dried, for example by patting or air drying.

A composition may be applied to the seeds using conventional coating techniques and machines, such as fluidized bed techniques, the roller mill method, rotostatic seed treaters, and drum coaters. Other methods, such as spouted beds may also be useful. The seeds may be pre-sized before coating. After coating, the seeds may be dried and then transferred to a sizing machine for sizing. Such procedures are generally known in the art.

If a composition is applied to the seed in the form of a coating, the seeds can be coated using a variety of methods known in the art. For example, the coating process can comprise spraying the composition onto the seed while agitating the seed in an appropriate piece of equipment such as a tumbler or a pan granulator.

In one embodiment, when coating seed on a large scale (for example a commercial scale), the seed coating may be applied using a continuous process. For example, seed may be introduced into the treatment equipment (such as a tumbler, a mixer, or a pan granulator) either by weight or by flow rate. The amount of composition that is introduced into the treatment equipment can vary depending on the seed weight to be coated, surface area of the seed, the concentration of the fungicide and/or other active ingredients in the composition, the desired concentration on the finished seed, and the like. A composition can be applied to the seed by a variety of means, for example by a spray nozzle or revolving disc. The amount of liquid may be determined by the assay of the formulation and the required rate of active ingredient necessary for efficacy. As the seed falls into the treatment equipment the seed can be treated (for example by misting or spraying with the composition) and passed through the treater under continual movement/tumbling where it can be coated evenly and dried before storage or use.

In another embodiment, the seed coating may be applied using a batch process. For example, a known weight of seeds can be introduced into the treatment equipment (such as a tumbler, a mixer, or a pan granulator). A known volume of the composition can be introduced into the treatment equipment at a rate that allows the composition to be applied evenly over the seeds. During the application, the seed can be mixed, for example by spinning or tumbling. The seed can optionally be dried or partially dried during the tumbling operation. After complete coating, the treated sample can be removed to an area for further drying or additional processing, use, or storage.

In an alternative embodiment, the seed coating may be applied using a semi-batch process that incorporates features from each of the batch process and continuous process embodiments set forth above.

In still another embodiment, seeds can be coated in laboratory size commercial treatment equipment such as a tumbler, a mixer, or a pan granulator by introducing a known weight of seeds in the treater, adding the desired amount of the composition, tumbling or spinning the seed and placing it on a tray to thoroughly dry.

In another embodiment, seeds can also be coated by placing the known amount of seed into a narrow neck bottle or receptacle with a lid. While tumbling, the desired amount of the composition can be added to the receptacle. The seed is tumbled until it is coated with the composition. After coating, the seed can optionally be dried, for example on a tray.

In some embodiments, the treated seeds may also be enveloped with a film overcoating to protect the fungicidal coating. Such overcoatings are known in the art and may be applied using conventional fluidized bed and drum film coating techniques. The overcoatings may be applied to seeds that have been treated with any of the seed treatment techniques described above, including but not limited to solid matrix priming, imbibition, coating, and spraying, or by any other seed treatment technique known in the art.

Treated Seeds

In one embodiment the disclosure is generally related to a seed that has been treated with a composition as described herein comprising a compound (e.g., a compound of Formula I, Ia, Ib, II, IIa, IIb, IIc, IId, III, or IV) as described herein. In some embodiments, the seed has been treated with the composition using one of the seed treatment methods set forth above, including but not limited to solid matrix priming, imbibition, coating, and spraying. The treated seed may be of any plant species, as described above. In other embodiments, a seed is treated with a composition as described herein, including formulating, mixing in a seed treater tank, or combining on a seed by overcoating one or more additional active ingredients. The additional active ingredient may be, for example, an additional pesticide. The pesticide may be, for example, an insecticide, a fungicide, an herbicide, or an additional nematicide as described herein.

The amount of a compound present on a treated seed sufficient to protect the seed, and/or the roots of a plant grown from the seed, against damage by phytopathogenic fungi can be readily determined by one of ordinary skill in the art. In an embodiment, treated seeds comprise a compound of Formula I, Ia, Ib, II, IIa, IIb, IIc, IId, III, or IV in an amount of at least about 0.005 mg/seed. In another embodiment, treated seeds comprise a compound of Formula I, Ia, Ib, II, IIa, IIb, IIc, IId, III, or IV in an amount of from about 0.005 to about 2 mg/seed, or from about 0.005 to about 1 mg/seed.

Having described the disclosure in detail, it will be apparent that modifications and variations are possible without departing from the scope of the claims.

Administration

In some embodiments, a compound (e.g., a compound of Formula I, Ia, Ib, II, IIa, IIb, IIc, IId, III, or IV) as described herein is used as a ACCase modulator. For example, in some embodiments, the present disclosure is directed to a method of modulating acetyl-CoA carboxylase (ACCase) in a biological organisim, wherein the method comprises administering to the biological organism a composition comprising an effective amount of a compound.

In some embodiments, the biological organism is an animal. For example, in some embodiments, the biological organism is a warm-blooded animal. In some embodiments, the biological organism is a mammal, including, for example, humans.

A compound described herein may generally be formulated in a composition comprising one or more biologically acceptable excipients and, optionally, another pharmaceutically active agent known to those skilled in the art.

Any suitable dosage may be administered. The compound or salt thereof chosen for a particular application, the carrier and the amount will vary widely depending on the species of the warm blooded animal or human or the particular disease condition being treated, and depending upon the effective modulatory concentrations observed in trial studies. The dosage administered will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular compound or salt thereof and its mode and route of administration; the age, health, or weight of the subject; the nature and extent of symptoms; the metabolic characteristics of the composition and patient, the kind of concurrent treatment; the frequency of treatment; or the effect desired.

A dosage unit may comprise a single compound, or mixtures thereof, with other compounds. The dosage unit may comprise diluents, extenders, carriers, liposomes, or the like. The unit may be in solid or gel form such as pills, tablets, capsules and the like or in liquid form suitable for oral, rectal, topical, intravenous injection or parenteral administration or injection into or around the treatment site.

EXAMPLES

The following non-limiting examples are provided for further illustration.

Example 1 ACCase Enzymatic Assay

Ustilago maydis acetyl CoA carboxylase (ACCase) was cloned, expressed, and purified as described (Weatherly et al, Biochem. J., 2004) and the test compounds were tested in a 96-well plate format. Primary in vitro screening consisted of obtaining dose response data at 100, 33, 10, and 1 μM inhibitor. Actives in the primary screen were re-tested to establish IC50 values.

Direct detection of the conversion of acetyl CoA to malonyl CoA by ACCase was not feasible, but during this process ATP is converted to ADP which allowed for detection through a standard reaction coupling with ADP recycling to the oxidation of NADH. Thus, ACCase activity was measured via kinetic OD340 measurements of the conversion of NADH to NAD in a coupled reaction involving the conversion of phosphoenolpyruvate (PEP) to lactate.

The complete 200 ul reaction mixture contained 52.5 mM HEPES (pH8), 2.625 mM MgCl₂, 1 mM ATP, 0.525 mM DTT, 11 mM NaHCO₃, 1% DMSO with or without inhibitor, lx pyruvate kinase/lactate dehydrogenase (PK/LDH), 0.3 mM NADH, 0.5 mM PEP, and 5 μg ACCase. The reactions were incubated at 30° C. for 10 minutes and then initiated by the addition of 0.33 mM acetyl CoA. The initiated reactions were read immediately via plate reader at OD340 and kinetic readings were acquired every 20 s for 15 minutes while keeping the temperature at 30° C.

A slope of the kinetic curve was determined by using the 2 to 7 minute data which was then calculated as percent inhibition relative to the no inhibitor control.

The primary screens were conducted in duplicate and the IC50's conducted in triplicate. Averages were reported along with standard deviation calculation to generate error bars.

Each plate contained its own controls and consisted of a DMSO only control, 5-fold titration series of soraphen from 2 μM to 3.2 nM, and an ADP coupled reaction control.

In order to effectively screen out non-specific modulators of pyruvate kinase and lactate dehydrogenase (the coupled portion of the reaction), a PK/LDH inhibition test was developed. The complete 200 μl reaction mixture contained 52.5 mM HEPES (pH8), 2.625 mM MgCl₂, 0.525 mM DTT, 11 mM NaHCO₃, 1% DMSO with or without inhibitor, lx pyruvate kinase/lactate dehydrogenase (PK/LDH), 0.3 mM NADH, and 0.5 mM PEP. The reactions were incubated at 30° C. for 10 minutes and then initiated by the addition of 66 μM ADP. The initiated reactions were read immediately via plate reader at OD340 and kinetic readings were acquired every 20 s for 15 minutes while remaining at 30° C.

A slope of the kinetic curve was determined by using the 2 to 7 minute data which was then calculated as percent inhibition relative to the no inhibitor control. Those compounds which had no significant PK/LDH inhibition at or above the 1050 in the ACCase assay, were considered to be valid modulators of only ACCase. The 1050 data for compounds disclosed herein is shown in Table 1A below.

Example 2 Fungal Growth Inhibition Assay

Spores were isolated from previously sub-cultured plates of Botrytis cinerea, Phytophthora capsici, Fusarium mondiforme, Fusarium viguliforme, Collectotrichum graminicola, and Diplodia maydis. All spores were filtered and collected in a sterile glass bowl to isolate the spores from the mycelia. The isolation and sub-culture plate condition for each pathogen is described below.

Spore isolation for B. cinerea: A 2-3 week old V8 (17%)+CaCO₃ (3 g/L)+20 g agar plate was removed from room temperature and the mycelia were treated with 5-10 ml of filter sterilized Triton X 100 (0.05%). The mycelia were scraped to re-suspend the spores. The spores were then collected in a sterile filter bowl containing a fluted piece of filter paper and poured into a conical tube.

Spore isolation for F. moniliforme: A 1 week old PDA (potato dextrose agar, pre-mix) plate was removed from 26° C. incubator with a light/dark 12 hour cycle and the mycelia were treated with 5-10 ml of filter sterilized Triton X 100 (0.05%). The mycelia were scraped to re-suspend the spores. The spores were then collected in a sterile filter bowl containing a fluted piece of filter paper.

Spore isolation for C. graminicola: A 1-2 week old oatmeal agar (pre-mix) plate was removed from 26° C. incubator with a light/dark 12 hour cycle and the mycelia were treated with 10-15 ml of filter sterilized distilled water. The mycelia were scraped to re-suspend the spores. The spores were then collected in a sterile filter bowl containing a piece of sterile cheesecloth and poured into a conical tube.

Spore isolation for F. virguliforme: A 2-3 week old PDA (pre-mix) plate containing cefotaxime (100 mg/L) and kanamycin (50 mg/L) was removed from 26° C. incubator with a light/dark 12 hour cycle and the mycelia were treated with 5-10 ml of filter sterilized distilled water. The mycelia were scraped to re-suspend the spores. The spores were then collected in a sterile filter bowl containing a fluted piece of filter paper and poured into a conical tube.

Spore isolation for D. maydis: A 3-4 week old PDA (pre-mix) plate was removed from 26° C. incubator with a light/dark 12 hour cycle and the mycelia were treated with 6-7 ml of sterile distilled water, scraped into a sterile petri dish, and smashed to open the pycnidia. The spores were then collected in a sterile filter bowl containing a fluted piece of filter paper and poured into a conical tube.

Spore isolation for P. capsici: Three to five days prior to the assay a 2-3 week old V8 (17%)+CaCO₃ (3 g/L)+20 g agar plate was removed from a dark 25° C. incubator and cut up into small chunks. One plate was separated into two deep well plates and rinsed with sterile distilled water three times. The cut up pieces were incubated under light in a sterile filter hood with 25 ml of sterile distilled water. On the day of the assay the water was removed and 5-7 ml of fresh sterile distilled water was added. One plate was incubated at 4° C. for 45-60 minutes and then placed at room temperature for about 45-60 minutes. The spores were collected in a sterile filter bowl containing a fluted piece of filter paper. The spores were vortexed in a conical tube for 30-60 seconds to remove the flagella of the zoospores after isolation.

After spore isolation, pathogen spores were counted on a hemocytometer to calculate the spores/ml. In 17% V8 liquid media containing 3 g/L CaCO₃, isolated spores were diluted to individual concentrations based on the growth curves at 48 hours of each pathogen. The spore concentrations for each pathogen were as follows: B. cinerea—10,000 sp/ml; P. capsici—300 sp/ml; F. monliforme—500 sp/ml; F. virguliforme—500 sp/ml; C. graminicola—3,000 sp/ml; and D. maydis—3,000 sp/ml.

Chemistry stocks were dissolved in DMSO at 2.5 mg/ml. Chemistry was diluted in a 96-well stock plate in five-fold dilutions to obtain a final concentration of 50, 10, and 2 ppm in vitro. The final concentration of the positive control after the five-fold dilutions was as follows: soraphen—0.5, 0.1, and 0.02 ppm. Negative controls on each plate included 2% DMSO, water containing spores and media, and a blank for background subtraction.

In a 96-well plate the spore solution, chemistries, and controls were combined to make the final solution concentrations mentioned above. Upon addition of the chemistry, an OD600 reading was done to assess chemical precipitation. The 96-well plates were incubated in plastic tubs containing wet paper towels under the following conditions, 25° C. in the dark for P. capsici and B. cinerea or 26° C. with light/dark cycle for C. graminicola, D. maydis, F. virguliforme, F. monliforme. Plate readings were repeated at 24 and 48 hrs. Visual ratings were performed at 24 and 48 hrs to check for precipitation and confirm efficacy. Visual and OD600 ratings of the chemistry at 48 hours were compared to the 2% DMSO control to determine the percent of pathogen growth inhibition.

Fungal growth inhibition for compounds disclosed herein against several fungal species is shown in Table 2A through 2F.

Example 3 Yeast Growth Inhibition Assay

Yeast cells (Ade2 strain) were grown in liquid YPD (1% yeast extract, 2% peptone, 2% dextrose) for 16 hours at 30° C. from previously sub-cultured plates of Saccharomyces cerevisiae. The OD600 of the overnight culture was checked via spectrophotometer and diluted to a concentration of 2×10⁴ cells/ml.

Chemistry stocks were dissolved in DMSO to a concentration of 10 mM. Chemistry stocks were further diluted in a 96-well stock plate to obtain final concentrations of 100, 33, 10 and 1 μM in 1% DMSO. The final concentrations of the soraphen positive control were 400, 40, and 3.2 nM. The negative controls on each plate included a background subtraction control containing yeast and 1% DMSO (without chemistry) and a second contamination control containing YPD (with no yeast) and 1% DMSO (without chemistry).

98 μl liquid YPD was added to 2 μl diluted stock of DMSO per well and mixed thoroughly. After mixing, 100 μl of the diluted yeast solution was added to bring the final yeast concentration to 1×10⁴ cells/ml or 2000 cells per well. An initial spectrophotometric reading at OD600 was conducted on the entire plate and served as the 0 hours time point used to subtract any background. The plate was then incubated for 24 h at 30° C. with mild shaking. At the 24 h time point all wells of the plate were re-suspended by pipette to yield a uniform suspension, then read again at OD600. The OD600 reading at 0 hours (background) was subtracted from the 24 h OD600 reading and all wells were compared to the negative control and subtracted from 100 to determine the percent inhibition. All experiments were conducted in triplicate. Averages were reported along with standard deviation calculation to generate error bars. Each plate contained its own controls and consisted of inoculated+DMSO, non-inoculated+DMSO, and a titration series of soraphen at 400, 40, and 3.2 nM. The results of growth inhibition for Saccharomyces cerevisiae are reported in Table 2F below.

Description of Synthesis

The compounds of Formulas I, Ia, Ib, II, IIa, IIb, IIc, IId, III, and IV may be prepared using methods known to those skilled in the art.

Example 4 Description of Synthesis of Compounds of Formula Ia

For example, the compounds of Formula Ia can be prepared as set forth in Scheme 1 below. More particularly, the optionally substituted 2-aminobenzophenone 1 may be reacted with 4-hydroxyacetophenone in the presence of citric acid at 120° C. to yield the desired 4-phenylquinoline derivative 3. Alkylation of the compound 3 with chloroacetamide 4 in the presence of potassium carbonate in acetone affords the desired compound of the Formula Ia where Y is NH₂, X is O, and susbtituents R³ to R⁶ are as defined with respect to Formula Ia above.

The 2-aminobenzophenone 1 described above can be prepared according to the general synthetic route depicted in Scheme 2. The optionally substituted 2-aminobenzoic acid 2 is cyclized to corresponding benzoxazine 3 by heating in acetic anhydride. Then, the compound 3 is reacted with phenylmagnesium bromide to give the corresponding N-acetyl 2-amino benzophenone which is subsequently tretaed with 6NHCl in ethanol to remove the acetyl group and yield the desired 2-aminobenzophenone 1.

Alternatively, the compounds of Formula Ia may be prepared using the general procedure illustrated in Scheme 3, below. More particularly, preparation of a 4-phenylquinoline 3 may be accomplished using a procedure similar to that described in Scheme 1, above. In the next step, alkylation may be carried out with methyl α-bromoacetate 4 to afford the corresponding methyl ester. The saponification of the methyl ester 5 with 1 NaOH in a mixture of THF and MeOH yields the corresponding quinolinylphenoxyacetic acid 6, wherein substituents R³ to R⁶ may be selected as defined above with regard to Formula Ia.

Example 5 Description of Synthesis of Compounds of Formula Ib

The compounds of Formula Ib may be prepared as generally set forth in Scheme 4 below. More particularly, the optionally substituted 2-aminobenzophenone 1 may be reacted with 2-acetyl-heteroaryl-acetamide 2b in the presence of citric acid at 120° C. to yield the desired compound 3 of Formula Ib. Susbtituents E and R³ to R⁶ may be selected as defined with respect to Formula Ib above.

The required acetyl-heteroaryl acetic acid derivative 2b may be prepared, for example, as generally illustrated in Scheme 5 below.

Alternatively, the compounds of Formula Ib may be prepared as generally illustrated in Scheme 6 below. More particularly, preparation of the 4-phenylquinoline derivative 3 may be accomplished by reacting of the optionally substituted 2-aminobenzophenone 1 with methyl 2-acetyl-heteroaryl-acetatate 2b in the presence of citric acid at 120° C. The saponification of the methyl ester 3 with 1 NaOH in a mixture of THF and MeOH yields the corresponding acid 4. Substituents E and R³ to R⁶ may be selected as defined with respect to Formula Ib above.

In a further alternative, the compounds of Formula Ib may be prepared as generally illustrated in Scheme 7 below. More particularly, preparation of the 4-phenylquinoline derivative 3 may be accomplished by reacting of the optionally substituted 2-aminobenzophenone 1 with 2-chloroacetyl-heteroaryl-acetate 2c in the presence of trimethylsilyl chloride (TMS-Cl). The saponification of the methyl ester 3 with 1N NaOH in a mixture of THF and MeOH yields the corresponding acid 4. Alternatively, ammonolysis of the ester 3 with NH₃ in MeOH yields the corresponding amide 5. Substituents E and R³ to R⁶ may be selected as defined with respect to Formula Ib above.

Example 6 Description of Synthesis of Compounds of Formula IIa

The compounds of Formula IIa may be prepared as generally set forth in Scheme 8 below. More particularly, the optionally substituted 2-aminobenzophenone 1 may be reacted with 4-hydroxyacetophenone in the presence of citric acid at 120° C. to yield the desired 4-phenylquinoline derivative 3. The intermediate 3 is then combined with bromoacetonitrile 4 to form the corresponding nitrile 5, which is subseqenetly converted to the corresponding tetrazole 5 with sodium azide in the presence of ammonium chloride in N,N-dimethylformamide (DMF). Substituents E and R³ to R⁶ may be selected as defined with respect to Formula IIa above.

Example 6 Description of Synthesis of Compounds of Formula IIb

The compounds of Formula IIb may be prepared as generally set forth in Scheme 9 below. More particularly, the optionally substituted 2-aminobenzophenone 1 may be reacted with a 2-(5-acetylaryl)acetonitrile 2 to form the acetylnitrile derivative 3, which may be subseqenetly converted to the corresponding tetrazole 4 with sodium azide in the presence of ammonium chloride in N,N-dimethylformamide (DMF). Substituents E and R³ to R⁶ may be selected as defined with respect to Formula IIb above.

Example 7 Preparation of 2-aminobenzophenones

The intermediate compounds (2-amino-3-ethylphenyl)(phenyl)methanone and (2-amino-3-methoxyphenyl)(phenyl)methanone were prepared using the procedures set forth below.

Preparation of (2-amino-3-ethylphenyl)(phenyl)methanone
